Description: Fits spatial mixture models, including spatial Gaussian
        mixtures and mixtures of spatial factor analyzers, to complete
        or incomplete data. Spatial decay can be represented by
        monotone I-splines or a normalized sigmoid. Missing entries are
        handled using a built-in partial expectation-maximization
        procedure for matrix-variate data. The spatial covariance and
        spatial factor analyzer models are described in Lu and
        colleagues (2026a) "Spatial Covariance Constraints for Gaussian
        Mixture Models" <doi:10.48550/arXiv.2601.07979> and Lu and
        colleagues (2026b) "Mixtures of spatial factor analyzers for
        tensor-variate data" <doi:10.48550/arXiv.2607.07887>.
